Self-Destructing Spiral Waves: Global Simulations of a Spiral Wave Instability in Accretion Disks
Jaehan Bae, Richard P. Nelson, Lee Hartmann +1
We present results from a suite of three-dimensional global hydrodynamic simulations which show that spiral density waves propagating in circumstellar disks are unstable to the gro…
Vortices in stratified protoplanetary disks : From baroclinic instability to vortex layers
P. Barge, S. Richard, S. Le Dizes
Large scale vortices could play a key role in the evolution of protoplanetary disks, particularly in the dead-zone where no turbulence associated with magnetic field is expected. T…
Vortex formation in protoplanetary discs induced by the vertical shear instability
Samuel Richard, Richard P. Nelson, Orkan M. Umurhan
We present the results of 2D and 3D hydrodynamic simulations of idealized protoplanetary discs that examine the formation and evolution of vortices by the vertical shear instabilit…
Structure, stability and evolution of 3D Rossby vortices in protoplanetary disks
Samuel Richard, Pierre Barge, Stephane Le Dizes
Large-scale persistent vortices are known to form easily in 2D disks via the Rossby wave or the baroclinic instability. In 3D, however, their formation and stability is a complex i…
